Howdy gents,

I have a DDM47s upper from early 2020. With a surefire socom sc2 it's overgassed, so I went to an a5 buffer system with an H4 buffer and it's still overgassed as all get up.

What gives?

shoot me a DM with the Lot Number on the barrel, please. It's located on the right side of the barrel around the 4 o'clock position.

Did DD tell you what the port size on your barrel was?
